Annlication filed mm, 1906. Serial No. 305,988.

countyof Brown and State of Illinois, havev invented a new and Improved SadIron, of which .the following'is a full, clear, and exact description.

This invention is an improvement in sad irons and has for an object, among others, to provide a comparatively cheap, simple and effective self-heating iron, presenting a neat appearance without any overhanging or cumbersome parts likely to interfere with its proper use. This object is accomplished by our invention, oneembodiment of which is hereinafter disclosed.

Reference is to be had to the accompanying drawings forming a part of this specification, in' which similar characters of reference indicate corresponding parts in all the figures. a

. Figure 1 is a vertical, central, lon itudinal section of our improved iron on the line '11 of Fig. 2, and Fig. 2 is a section on the line 22 of Fig. 1. i

In the drawings, 1 indicates the body portion of the iron, and, as shown, consists of a single casting containing a fuel tank and a burner, and provided 'with cooling means,

' and having formed at the top thereof a handle 2. This is an important feature of construction, since it obviates the necessity of suspending these necessary elements from various parts of the supporting structure. The body of the iron is composed of a base 3, atop 4, sides 5, ends 6 and 6? and partitions 7 and 8 dividing the interior of the structure into three substantially equal compartments.

On the base 3 at each end thereof are sup-' ports 9, having forked upper ends for receiving the ends of atubular burner 10, having apertures in its under side for the purpose of rojecting a series of small flames toward the ase 3.

The compartment between the partitions 7 and 8 is provided with an asbestos mat 7 restin on the partition 7 and held from slip- 5 5 between the top 4 and partition 8 constitutes ing dividing it into compartments, a burner ping t erefrom by a projecting toe 7 on said artition. This compartment also contains iarge ventilating holes 11 at each side, for permitting a free circulation of air between the partitions and keeping this part of the body of the iron in a cool condition. The space atank for containing fuel for the burner 10 in the lower compartment-of the body, and has a filling plug 12 screwed or otherwise secured at some convenient point on the to 4.

The handle 2 has a bore 3, in which a pis tonhead 13 can be reciprocated by meansof a screw-threaded cylinder head 16, which forms a guiding means for the stem. The opposite cylinder head 17 is made integral with the handle and is connected to the. top of the fuel tank by a pipe 18. Slidable on guides at each side of an opening in the end 6 extending from the compartment 5 to near the base 3, is a damper 19 having a handle 20 for sliding it on the guides'and regulating the supply of air admitted to the burner. The opposite end of the burner chamber has at the top a hole 21 at each side (one of said openings being shown in Fig. 1) for expelling the products of combustion. bottom of the tank, is screwed a pipe 22 connected to a cut-off valve 23, and leading therefrom to the burner chamber over and near the top of the burner, said pipe forming a U, with one end connected to the burner'at its under side near the point where the pipe enters the burner chamber.

In the operation of the iron, the tank is filled with the liquid fuel through the filling plug 12, to about the height as shown in Fig.

1, leaving a space above the fuel in which air.

can be compressed by the piston 13. When sufficient pressure is attained for proper feedin the valve 23 is opened and theburner lig ted in the usual manner. The numerous flames directed to the base by the burner will heat this portion very hot, the temperature of which can be regulated by the valve 23. The artition 7 will be much cooler than other arts of the, burner chamber and will have t e major ortion of its heat confined by the mat 7 thereby, in conjunction with thelventilating holes 11, lowering the temerature of the air chamber and keeping the dition.

Having thus described our invention we claim as new and desire to secure by Letters In the wall 6, near the el above in the tank in acool and safe con Patent:

1. In asad iron, the combination of a casing, a handle fixed to the top of the casing, a piston in the handle, partitions in the cas- IIO in the lower compartment, the upper comthe tank, and a feed pipe leading from' the partment forming a fuel tank, and the central compartment forming a cooling chamber, a pipe connecting the handlewith the tank,- and a pipe connecting the tank with the burner.

2; In a sad iron, the combination of a casing, a handle'fixed at the top of the casing, partitions in the casing dividing it into compartments, a burner in the lower compartment, the upper compartment forming a fuel tank and the central compartment forming a cooling chamber, a pi e connecting the han-' a pipe connecting the.

dle with the tank, an tank with the burner.

3. In a sad iron, the combination of a casing, a handle fixed at the top of the casing,

partitions in the casing dividing it into compartments, a burner in the lower compartment, the upper compartment forming a fuel tank and the central compartment forming a cooling chamber, a pipe connecting the handle with the tank, a pipe connecting the tank with the burner, and means for forcing air into the tank. i

4. A sad iron com rising a hol ow body, partitions in said bo y dividingit into compartments, a burner in the lower compartment, the u per com artment forming a fuel tank and t e centra compartment formin an air chamber having ventilating holes, an a feed pipe leading from the tank to the burner.

5 A sad iron comprising a hollow body, a

hollow handle fixed at the top of said body, partitions in said body dividing it into compartments, a burner in the lower compartment, the upper com artment forming a fuel tank and the central compartment forming an air chamber havin ventilating holes, 'a piston in the handle, a apted to force air into tank to the burner.

v6. A sad iron comprising a hollow body, partitions in the body dividing it into compartments, anopening at the back end of saidbody, a burner in the lower compartment, the upper compartment forming a fuel tank and the central com artment forming a cooling chamber having an holes, and a damper slidablein the opening at the back of the ody of the iron, to regulate the admission of air to the burner.

7. A sad iron comprising a hollow-body, partitions in said body dividing it into three compartments, form' respectively a burner chamber, an air cham er and a fuel tank, a hollow handle atthe top of said body, containing a piston for forcing air into the tank, an opening at the back end of the body, a damper slidable in the opening, and a fuel pipe having a regulating valve connecting the tank and the burner. o

8. In a sad iron, the combination of a casing of substantially uniform, horizontal section throughout, a handle fixed to the top of the casing, a piston in the handle, partitions in the casing dividing it into compartments, a burner in the lower compartment, the upper compartment forming a fuel tank and the central compartment forming a cooling chamber, means for connecting the handle with the tank, and means connecting the tank with the burner.

In testimony whereof we have signed our 'names to this specification in the presence of
